Since the Reform and Opening up, the social economy has developed rapidly. However, the economic development is at the expense of the environment. In order to ensure the sustainable development and the harmony between human and nature, it is necessary to develop modern green buildings. The engineering cost plays a very important
role in the construction engineering. The purpose of the enterprise is to make profits. Only by improving the profitability of the enterprise can more benefits be created for the society. The engineering cost is the basic measure to judge the profitability of the project. Through the engineering cost, the ability to judge the construction cost and benefit can be strengthened.
    This paper explains the green building construction technology and project cost from several aspects: including the introduction of green building materials and green construction technology to analyze the important influence of green building on people’s production and life; including the application of new technology and materials of earthwork, reinforced concrete and waterproof engineering in green building to analyze the necessity of engineering cost in green building. Although green building technology is still a new technology, is a comprehensive, systematic technology, but green building technology has  very fresh vitality, countries around the world are actively exploring it.

改革开放以来，社会经济飞速发展，然而经济的发展是以牺牲环境为代价，为了保证可持续发展，做到人与自然和谐相处，发展现代绿色建筑便显得非常必要；工程造价在建筑工程中所发挥的作用非常大，企业以盈利为目的，同样企业盈利能力提升才能为社会创造更多效益，工程造价是判断工程盈利能力的基础措施，通过工程造价可加强对建筑成本与效益的判断能力。

      本文从多个角度对绿色建筑施工技术与工程造价的相关内容展开了阐释：包含绿色建筑材料和绿色施工技术的介绍来分析绿色建筑对人们生产、生活的重要影响；包含对绿色建筑中土方工程、钢筋混凝土工程和防水工程的新技术、新材料在绿色建筑工程中的应用分析绿色工程中工程造价的必要性。尽管绿色建筑技术目前还是一项新技术，是一项综合的、系统性技术，但是绿色建筑技术有着非常鲜活的生命力，世界各国都在对其进行积极探索。它所涉及的范围、内容比较广，需要各个领域、各个部门的通力合作、共同研究。

In recent years, with the rapid development of China’s urbanization and the continuous improvement of people’s living standards, people’s life style and residential demand have gradually developed from “quantity” to “quality”, and the construction of urban communities is moving towards diversified and compound development. Under the background of large-scale commercial housing development and construction, the closed community mode and spatial organization are the main existing forms of residential community in China in the past decades. With the change of time, the closed community model and spatial organization exposed many problems, such as the fragmentation of urban space, and the exclusion of community and urban space, which destroyed the coherence of urban traffic grid, and its barrier to urban roads is also one of the important factors causing serious urban traffic congestion in China. In the process of urban road construction which ignores the road density, the uncontrolled increase of road scale leads to wide road becoming the typical configuration of urban traffic in China, which makes traffic congestion, the disappearance of street life, and the plunder of public resources, which greatly inhibits the sustainable development of the city.
    This book is divided into eight chapters, from different angles and content of the open community space construction process were analyzed and elaborated in detail, found the open community promotion and construction process of various problems, and put forward the corresponding suggestions, measures and methods.
